Diagnostic description

Habitus: Fig. 7 View Figs 7–12. 7–8 . Wingless. Body length: 10.2–11.9 mm. Body shiny black; basal ¾ of the femora and basal ½ of the tibiae dark brown; rest of the legs, antennae and mouthparts reddish brown. Elytral microsculpture transverse. Head average, eyes moderately bulging, mandibles long and acute. Pronotum elongate, cordiform, hind angles right angled, sharp; two pairs of lateral setae. Elytra narrow, humeri wholly effaced, striae deep, entire, with traces of punctation; third interval with three setae in most specimens (four setae on both elytra of one paratype and on the right elytron of another); subapical sinuation very deep; apex with a small acute tooth at sutural angle. Last visible abdominal ventrite with one pair (♂) or two pairs (♀) of setae along its apical margin. Legs slender; fourth metatarsomere without subapical dorsolateral setae, apical lobes parallel, the outer lobe 1.5 times longer than the inner lobe. Male genitalia: Fig. 8 View Figs 7–12. 7–8 . Middle section of the median lobe straight in lateral view, feebly arcuate distally, apex triangular in lateral view, very short; endophallus without sclerotized structure, except for a subapical denticle. Female genitalia: unstudied.

Comparisons

Habitat

Riparian in the montane forest on the Western slope of the Andes , at around 2200–2250 m a.s.l. The 2100 m elevation indicated on the labels of the specimens collected in 2010 is wrong, the correct elevation is 2200 m.

Geographic distribution

Southern end of the Chocó biogeographic region in northwestern Ecuador. Only known from the type locality, probably microendemic.
